95 Civic Head Gasket or Water Pump?
It seems as though my car only overheats after 20+ min of me driving it. When I get home, the reservoir is usually full of coolant (sometimes you can see it has overflowed).
Also, the faster I go, the more the temp gauge goes down whenever the car decides to overheat. lmao.. The hell?
I just installed a new thermostat, radiator cap and new radiator. All OEM.
No white smoke. No milky coolant. Fan comes on. When bleeding my coolant today, I did see slight steam/smoke coming from the reservoir/reservoir tube.

Re: Head Gasket or Water Pump?
So I did this, and my fan comes on.
Does this mean that I have a bad fan switch or everything is running like it is supposed to?
Looking back, I want to say that my car only overheats after I stop for a while
.
I then have to drive fast as fukk to get the temperature gauge down.

Re: Head Gasket or Water Pump?
I was thinking water pump too. However, I thought a bad water pump would leak before anything. Also, when I take the spark plugs out, what am I looking for (oil, coolant, etc)?

Re: Head Gasket or Water Pump?
I agree, it is most likely the pump.
Question, you said, "but it does come on (about 10 secs", does that mean it only stays on for that 10sec and then turns off and keeps running with jumper in place, replace ECT switch. 94

Re: Head Gasket or Water Pump?
When I was bleeding my system, the fan did come on. It stayed for about 10 seconds, and then cut off. When I had the jumper in the fan switch, the fan continuously ran. Does this mean I have a bad fan switch, or everything is working like it's supposed to?

Re: Head Gasket or Water Pump?
if the fans run when the car is overheating the fan switch is likely ok but they shouldnt be turning off
the next time it starts rising and the fans turn off, i would quickly jumper the fan switch and leave the fan on to see if the temp goes down, if it does then replace the fan switch with a Honda fan switch

Re: Head Gasket or Water Pump?
wait, now im thinking the thermostat might be bad, idle the car and check the lower radiator hose back where it meets the thermostat housing, make sure it gets hot as the car warms up, it might not be and that would mean you need a new Honda thermostat

Re: Head Gasket or Water Pump?
Should the bottom hose be full of coolant though?

Re: Head Gasket or Water Pump?
I can confirm that the bottom hose gets hot at operating temperature. I just changed it three days ago.

Re: Head Gasket or Water Pump?
Thanks for replying! I've heard about the fins being eaten off from corrosion. I just don't see how it's possible since all I've been using is 50/50. Still a possibility I would assume. And definitely going to look for coolant in the cylinder head.

Re: Head Gasket or Water Pump?
A $20 compression test would rule out a failing head gasket and prevent you from having to pull the head. Then you would just pull the water pump to see if they are indeed bad. It is possible you have a hairline crack in the block but this isn't all too common.

Re: Head Gasket or Water Pump?
Happend to my accord. Same symptoms....blown headgasket. Exhaust gases is pushing coolant back out into the resivior. When engine cools, coolant remains in resivior and radiator is low. Drive and repeat....but yes def do a pressure test.

Kinda. The coolant in the reservoir goes down overnight. And the radiator stays full. Definitely going to do a pressure test.

Re: Head Gasket or Water Pump?
When you bled the system did you make sure the nose of the car was raised some? i.e. parked on an incline with the nose up?
